[Wlug] port security question

[Simeon MacMillen]

I'm trying to set up Echolink (amateur radio software) on Ubuntu
(through WINE).  My computer failed the firewall tests -the
troubleshooting material recommended the following:

Allow UDP destination ports 5198-5199 between Internet and PC in both directions
Allow TCP (source port any, destination port 5200) from PC to Internet

What security risks do I introduce by doing this?  (Is it worth the risk?)

Thanks,
Simeon MacMillen

P.S.  I've been on the Wlug mailing list for a year, though I've only
managed to make it to one meeting so far.
